It's really all about prestige, the show factor and being able to say I'm driving a more exclusive engine. Otherwise, there is no objective advantage any more.
I'm also surprised at the weight of this thing. In EU trim 2255kg! That is enormous, even considering all wheel drive and the long wheel base.
Another factor that I can't quite understand is why they place the turbo chargers outside of the engine V, and not inside as almost all modern car makers do (for better throttle response, to minimise turbo lag). Maybe BMW thought that with 6.6l displacement this is not really necessary.

It is not certain how much of the difference are due to the larger motor, as it could also be the result of additional standard equipment on the M760i. The difference while significant, really isn't that bad. To put it into perspective the M760i weight about the same as the S63 4Matic with 5.5L V8.
Since this motor is borrowed directly from Roll Royce, obviously the turbocharger layout and location are retained. I really don't think turbo lag is going to be a concern with this motor.
Novitec and Mansory have tuned this V12 to 708hp and 740hp on the Rolls Royce Ghost and Wraith. I think we will see the M760i run high 11s 1/4 mile stock and maybe into the high 10s with a tune.
